How Long Does Nicotine Take To Leave The Body
How long does it take for nicotine to leave your body (urine and blood stream) after you stop smoking?
How long does it take for nicotine to leave your body (urine and blood stream) after you've stop smoking?
It varies: Nicotine metabolism is complex. Most nicotine is metabolized in the body to co-nicotine, and this is what is tested for. Nictotine is 1/2 gone after 2 hours, co-nicotine about 20. It takes about 5 1/2 lives for a drug to be "97% gone". 10 half lives for 99.9% another source says a urine test can be positive 7 to 20 days after smoking. ...Read more
Can nicotine chewing gum damage your liver? Is milk thistle pills with cholin, completely safe to take for liver Health?
Rather safe: Nicotine isn't a particularly concerning chemical in liver disease. If you have to choose your "ills" nicotine gum is safer than smoking cigarettes. Milk thistle, which is often combined with choline, is also relatively well tolerated. It does have some side effects mostly benign gastrointestinal upset (which even a sugar pill can cause).If you don't have liver disease is less clear of a benefit ...Read more
Each cigarette: Contains about 1 mg of nicotine, and its half-life is about 2 hrs. It also is multicompartmental, meaning it can be "accumulated" in adipose tissue, detoxified to cotinine by cytochrome p-450 enzymes, so eliminaion entrely can be complicated by the direct half life, and then the leeching from the fat cells. It's complicated! ...Read more
Can 'vaping' (e-cigerettes) with nicotine in a propylene glycol solution cause elevated liver enzymes. Not sure if nicotine has an effect on liver? Ty
No: Nicotine has no adverse effect upon the liver unless you had a major overdose which only happens with the administration of large doses of nicotine. These doses cannot be met by smoking or vaping. Propylene glycol won't cause problems either. I would worry about chronic lung damage and nicotine addiction. If your liver enzymes are elevated, your doctor needs to find out the reason. ...Read more

I started smoking 8 years ago. I am quitting. How long will it take for my lungs to be normal? How long until my body is nicotine free?

If someone who has never smoked before, takes only one really weak puff from a cigar, how much nicotine is absorbed? How long for cotinine to leave?
No real damage: From one very weak puff of a cigar and the effects will leave your body very quickly. The real issue seems to be prevention from starting smoking. Cigars are just as dangerous as cigarettes. Avoid the slippery slope to smoking. Peace and good health. ...Read more
How long does it take for medazepam (using it if necessary in low dosage) to be out of the body? I read that it doesn't damage liver or kidneys. True?
Taking 4 mg alprazolam for 10 years. I have a elevated liver count and drs. Are attempting to diagnose. Wonder how long it will take to be out of body?
Alprazolam: Please do not stop Alprazolam suddenly. It is a habituating drug and you will experience withdrawal -- possibly including seizures. You have been on a relatively high dose for a long time, and tapering over time will be necessary. Please work with your physicians on this, rather than trying to get it out of your body by stopping it yourself. Best wishes. ...Read more

After a cigarette:
The average smoker with 1 MG of nicotine, after an hour or two, a trace is still left. The nicotine is metabolized in the liver and there is nothing to interfere with the breaking down of the substance.
The metabolite of nicotine is eliminated in the kidneys, which can be detectable in the urine for at least a week in the typical smoker. Insurance companies may test for the metabolite. ...Read more
2-3 days: nicotine is a very short-acting drug, and its main metabolite cotinine is too. After a single cigarette, levels will usually only be detectable for 24 hours, and most regular smokers will be detectable for 3 days or so. Depends on how it is tested, with oral swabs picking it up for longer, blood tests have a shorter window, urine is in the middle. Hair tests can go back months. How about stopping? ...Read more
Probably one day whi: Probably one day, which is a guess (24 hrs.) it's half life is 2 hrs, and it is metabolized by the liver and excreted by the kidneys into the urine. In a heavy smoker there be a higher plasma nicotine concentration and it may take 2 days. This is an educated guess. ...Read more
I gave up smoking in 1970 but my feet are still addicted. They want to go into any tobacco store I pass. I still have to be very firm with them and order them to walk in the opposite direction.
But I did quit. With less damage than if I had continued. ...Read more
24-48 hours: nicotine is usually not what is tested for, but its main metabolite cotinine. Nicotine is extremely short-acting - that is why people smoke 20 cigarettes a day (or about one an hour when awake). Cotinine lasts longer, and can be found in blood for 1-2 days and in urine for 2-3 days. Oral swabs can detect it potentially for slightly longer. ...Read more
Depends: Elimination of nicotine from the body is determined by half-life. Nicotine's half-life is 24-48 hours. In general, 3 to 5 half lives are necessary to eliminate it from your system. That means from 3-6 days. The withdrawal however lats much longer since your system "craves" it. I know it hurts (i went through it a number of years ago) but it is surely worth it. Hang in there. ...Read more
